Matter radii of light halo nuclei
Abstract
We re-examine the matter radii of diffuse halo nuclei, as deduced from reaction cross section measurements at high energy. Careful consideration is given to the intrinsic few-body structure of these projectiles and the adiabatic nature of the projectile-target interaction. Using Li, Be and B as examples we show that data require significantly larger matter radii than previously reported. The revised value for Li of 3.55 fm is consistent with three-body models with significant -intruder state components, which reproduce experimental Li momentum distributions following Li breakup, but were hitherto thought to be at variance with cross section data.
